Development and validation of an Arabic questionnaire to assess dentist knowledge on managing deep caries cavities

Abstract Introduction: The interconnection between oral health and systemic well-being is widely recognized, with dental caries being a prevalent global oral disease. This study focuses on the development and validation of a unique Arabic-language questionnaire to evaluate dentists' knowledge and skills in managing deep caries. Aim To create and validate the first Arabic questionnaire specifically for assessing dentists' competence in diagnosing and managing deep caries cavities. Methods The study adopted a multi-stage approach, including translation and adaptation of existing questionnaires, addition of new items by experts, and a thorough validation process. A balanced sample of 20 dentists from Damascus University Faculty of Dentistry participated. The questionnaire encompassed items divided into categories of diagnosis, treatment, and tools. Statistical analysis for internal and external validity, reliability, and other factors was conducted using SPSS. Results The questionnaire demonstrated high internal consistency (Cronbach's Alpha = 0.804, 0.879 for standardized items) and good test-retest reliability. Some items showed strong positive correlations, while a few indicated weaker correlations, revealing areas for potential refinement. The study highlighted significant correlations in most parameters, affirming the questionnaire's reliability. Conclusion This research successfully developed and validated the first Arabic-language questionnaire for assessing dentists' knowledge in managing deep caries cavities. The methodology ensured the tool's reliability and validity, with practical implications for dental education and practice in Arabic-speaking regions.
